The Wheatstone Project has been under construction within the Ashburton North Strategic Industrial Area, near Onslow, since December 2011.

The US$34 billion project includes two LNG processing trains with a total capacity of 8.9 million tonnes per year, plus a 200 terajoules per day domestic gas plant.

The Wheatstone joint venture participants have committed more than A$250 million to critical and social infrastructure in Onslow, including a new hospital, airport, power and water service upgrades, a new shire administration centre, swimming pool, housing, and road improvements.

The Wheatstone Project is a joint venture between the Australian subsidiaries of Chevron, Kuwait Foreign Petroleum Exploration Company, Woodside Petroleum and Kyushu Electric Power Company, together with PE Wheatstone, part-owned by JERA.
